Carlos Santana was scratched from the Indians’ lineup yesterday amid concerns that he might be dealing with post-concussion symptoms and sure enough he’s been placed on the seven-day concussion disabled list.

Cleveland also placed Nick Swisher on the 15-day disabled list with a hyperextended left knee suffered Monday, shutting down the first baseman after he hit just .211 with three homers and a .631 OPS in 49 games.

Of course, Swisher’s production looks great compared to Santana’s horrendous start to the season, which includes hitting .159 with 46 strikeouts in 50 games. Santana does have a league-leading 43 walks, but he’s looked lost at the plate all season in addition to struggling with a transition to third base defensively.

Santana previously was sidelined by a concussion in 2012 and these recent symptoms stem from being hit in the mask by a foul tip while catching Sunday.

Ken Rosenthal of The Athletic reports that the Angels will acquire second baseman Ian Kinsler from the Tigers. It is not known yet what the Tigers will receive in return. Kinsler had to waive his no-trade clause in order for the deal to happen.

Kinsler, 35, hit .236/.313/.412 with 22 home runs, 52 RBI, 90 runs scored, and 14 stolen bases in 613 plate appearances for the Tigers this past season. He’s in the final year of his contract and will earn $10 million for the 2018 season.

The Angels were certainly looking to upgrade at second base and did so with Kinsler. They were also reportedly interested in Cesar Hernandez of the Phillies.
